Evaluation of findings in carpal tunnel syndrome during surgery in patients referred to reconstructive surgery ward

Carpal tunnel syndrome [CTS] is the most common focal mono-neuropathy of median nerve in carpal tunnel. Prevalence is 2.7-5.8% and is more common in female than male. The most important diagnostic method is electrophysiologic study of median nerve. This case-control study has done on 34 patients with CTS and 44 healthy cases underwent electrophysiologic study. The diameter of nerve was measured at site of compression and also at a more proximal site in patients. In CTS group increased significant distal latency in motor and sensory conduction and proximal motor latency of median nerve was noticed. The altitude of sensory median nerve and conduction velocity of median nerve in CTS group was decreased significantly. Thenar atrophy was seen without relation with severity of nerve compression. The nerve diameter was decreased in severe cases of CTS group without significant differences. In CTS severity of anatomic changes are not the same as changes in electrophysiologic study

prevalence of metabolic syndrome according to different criteria and its associated factors in type 2 diabetic patients in Kerman, Iran

Metabolic syndrome is highly prevalent in type 2 diabetics and is a strong risk factor for cardiovascular diseases in such patients. The aim of this study was to determine the prevalence of metabolic syndrome according to the three criteria of ATPIII, IDF and the new criteria for metabolic syndrome diagnosis in Kerman, Iran. This cross-sectional study was performed on 950 diabetic type 2 patients. Data was analyzed by independent t-test, chi-square and logistic regression using the SPSS [revision 20] software. The prevalence of metabolic syndrome in Kerman was 73.4, 64.9, and 70.4%, according to the above criteria. Fasting blood sugar, gender, triglyceride, HDL, waist circumference, and systolic blood pressure were related to the prevalence of metabolic syndrome according to the abovementioned criteria.The prevalence of metabolic syndrome is high in type 2 diabetic patients and the above-mentioned factors exacerbate the situation

Effects of iron deficiency and iron deficiency anemia on visual evoked potential in women

Visual evoked potential is one of the main methods to investigate visual pathway. Some studies in children show that iron deficiency anemia affects on visual evoked potential waves. In this study, we evaluated the effect of iron deficiency and iron deficiency anemia on visual evoked potential in adults. This cross sectional study was conducted on 99 non-pregnant women. Patients divided into three groups. Women whose ferritin and hemoglobin levels are less 15 ng/1 and 12 mg/dl placed in iron deficiency anemia group, women whose ferritin level is less than 15 ng/1 and hemoglobin level is more than 12 mg/dl, placed in iron deficiency group and women whose ferritin and hemoglobin levels are more than 50 ng/1 and 12 mg/dl, chosen as control group. Visual evoked potential was done from both eyes and the results evaluated by ANOVA test. The average of N75 latency was 65.24 +/- 5.06 miliscecond in anemia group, 66.27 +/- 7.77 miliscecond in iron deficiency group and 67.19 +/- 6.79 miliscecond in control group. The average of P100 latency was 101.60 +/- 9.05 miliscecond in anemia group, 102.75 +/- 7.91 miliscecond in iron deficiency group and 100.67 +/- 7.34 miliscecond in control group. The average of N135 latency was 139.18 +/- 31.21 miliscecond in anemia group, 144.81 +/- 10.73 miliscecond in iron deficiency group and 141.81 +/- 10.73 miliscecond in control group. There is no significant difference between the average of waves' latency in iron deficiency and anemic groups with control group. Iron deficiency and iron deficiency anemia don't make any disruptions on visual evoked potential and are not considered as confounding factor of visual evoked potential in adults
